How to resend email for the seller

Hi there,

I created a code to resend email to the seller. This code?

dddd

function resend_payment_completed_email() {
    $url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

    if ( isset( $_GET['order_id'] ) && absint( $_GET['order_id'] ) && strpos($url,'video-gravado') === false) {
        $order_id = absint( $_GET['order_id'] );
        $order    = wc_get_order( $order_id );

        if ( $order && 'completed' === $order->get_status() ) {
            // Get the email class instance
            $email_class = WC()->mailer()->get_emails()['WC_Email_Customer_Completed_Order'];

            // Send the email
            $email_class->trigger( $order_id );

             // Send the email to seller
             $vendor_id = get_post_meta( $order_id, '_dokan_vendor_id', true );
             if ( $vendor_id ) {
                 $seller_email = dokan()->vendor->get( $vendor_id )->get_email();
                 if ( $seller_email ) {
                     $email_class->trigger( $order_id, $seller_email );
                 }
             }
             echo "<script>alert('Seu pedido foi reenviado com sucesso!')</script>";
            // Output a success message
            echo "<script>window.close()</script>";
            exit;
        }
    }
}
add_action( 'wp_loaded', 'resend_payment_completed_email' );
